To all whom it may concern:

Be it known that 1, ROBERT C. Jones, a citizen of the United States of rhnerica, and a resident of New Gumberland, county of Hancock, and State of West Virginia, have invented certain new and useful Improvements in Antoniatically-Operated Temper- Screws, of which the following is a specification.

My invention relates to'new and useful improvements inwell-drilling apparatus, and more particularly to an automatic device for letting out or paying out the temper-screw; and itconsists in the particular construction, arrangement, and combination of partswhich will hereinafter be fully described.

The object of the invention is to provide a device whereby the temper-screw of welldrilling apparatus is automatically let out as the drillingt0ols sink deeper in the well.

A further object of the invention is to provide a simple, strong, and durable mechanical device for oil, gas, or Artesian well drilling, which will automatically pay out the temper-screw much more accurately than can be done by the most experienced welldriller.

In describing the invention in detail reference is herein had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the invention. Fig. 2 is an inner face view of the ratchet mechanism, and Fig. 3 is an enlarged vertical section through the lower portion of the temper-screw.

vReferring to said drawings, in which like reference-numerals designate like parts throughout the several views, 1. indicatesthe ordinary walkin -beam, which has'inounted upon its end a sprin supported beam 2, on the front end of whic is supported the crossshaped head '3 of the temper-screw stem 4. Said beam 2 is mounted upon suitable springs 5, borne by the end of the walking-beam, as shown-thus forming a yieldable support for said stem.

The temper-screwb is supported between the reins 7 of the stem 4 in t e usual way and has a longitudinal groove 8 thereinin-which a key 9, carried by a sleeve 10, in which'said screw is longitudi ally movable,.i s adapted. to slide. Said s eeve *isf'integr'al with or is rigidly attached. to a bevel gearlflwhich' is supported by a sup ortin racket 12, said supporting-bracket ing bolted to the rear glowing said ,springs recoil.

face of the jacket 13, which incloses the ordinary boxing 14, carried by the ends-.ofx-the reins 7, the said rear faceof the jacket being made rectangular in form for the purpose instead of rounded, as ordinarily employed.

Formed integral with the jacket 13, on the front face thereof, is a boss 15, throughwhich the adjusting-screw 16 ordinarily employed for ad'usting' the boxing 14 is pro ected. Journa ed upon the boss 15 is a bevel-gear 17, which interrneshe s with the bevel gear 1 1, and formed integral with the bevel-gear 17:01 rigidly attached thereto on its outerface is a. pinion 18, which meshes wth a gearwheel 19, 7o journaled upon the outer endof a-boss 20 carried by of the reins 7.. Also -journaled upon the boss 29 and rigidly attachedto. the inner face of the ear-wheel 19iis a ratchetwheel 21, the teet of which are adapted to be successively engaged by a spring-controlled pawl 22, which is ivotally [mounted at 23 upon a lever 24, 't e inner end of which is loosely mounted on said boss 20 on the inner side of the ratchet-wheel 21. A rod '25, rendered adjustable in lengthbythe 'employment of a turnbuckle 26, is sus ended vfrom the walking-beam 1 at a. suitable point, the lower end of said rod be' rigidly attached I to a slide 27, which is ad ustably mounted upon the outer end of saidi'lever 24, asstscrew 28 being provided for securing said slide in adjusted position on the leven TF1 The drilling-tools being suspend d 'from' v the temper-screw and the temper-screw be,- 0 ing suspendedv from the]spring.-supportedv beam 2, the weight of said tools and cable is borne by the s rings 5.
